emm, yes, use stick to transfer KU is a bad idea 
perhaps KU would be better suited to created and use at the same time than to transport it over long distances.
maybe transfer SU instead HU and convert SU to HU is better, but losses are indeed not negligible.
I think, do you create direct transmission only for energy that is suitable for transmission?
In fact, if we can get enough EU, we don’t seem to need these things
